windmill-infer-args

A TypeScript library for inferring arguments from code snippets in various languages for Windmill workflows.

Installation

npm install windmill-infer-args

Usage

import { inferArgs } from 'windmill-infer-args'

// Example schema
const schema = {
	properties: {},
	required: []
}

async function main() {
	// Infer arguments from Python code
	const pythonCode = `
def main(name: str, age: int = 30):
    print(f"Hello, {name}! You are {age} years old.")
  `

	const result = await inferArgs('python3', pythonCode, schema)
	console.log(schema)
	// Output will contain properties for 'name' and 'age' with proper types
	// 'name' will be in the required array since it has no default value
}

main()
